partial ver- Fig. l is an elevation, in

arranged in V tical section, ofl my structure place in a flushing tank;

Fig. 2 an elevation of the manipulator and dash pot, in a plane at right angles to that of Fig. l, on a larger scale; Fig. 3van elevation, in the plane of Fig, l of't-he parts shown in Fig. 2, in partial secption; and Fig. 4 a fragmentary section or the fiushing valve.

In the drawings l() indicates a tank havg ing suitable storage capacit-y and provided with a water inlet-nozzle of any desired construction which, in the drawings, is of a special form which is the sub]ect matter of my above-mentioned application.

Leading from the tank l() is a discharge litting 29 to which the discharge pipe 30'is attached. Fitting 29 is, in the main, quite similar to ordinary discharge fittings, being provided at vits upper end with a valve seat 3l. However, in my construction the throat ofl fitting 29 is transversed by cross'bar 32 carrying an upwardly proJectmg guide pin 33 which serves as a guide for my improved combined flushing valve and over-flow. This improved element comprises an overflow pipe 35 and a flexible valve ring 36,

the pipe 35 having a length sufficientfto.

roject above the normal water level desired within the tank lO, and the ring 36 serving to rest upon valve seat 31 and there-by obstructing outflow through fitting 29.

In order to hold ring 36 vin place under such conditions as to properly cooperate with seat 3l, I providethe lower end of the overflow pipe 35lwith a threaded ring 37 having a circumferential flange 38 provided with a slightly thickened shoulder 3Q at its junction with the main body of the ring 31:' By this construction the outer portion o f ring 36, when it contacts with seat 3l, is free from contact with ring 38 so that the head of water in the tank may act upon ring 36 and hold it on its seat when the parts are in the positions shown in Fig. 4. A threaded ring 40 screws upon ring 37 so as to hold the packing ring 36 in place, and is `thereby permitting pipe 35'to seat without provided with .a diametrical `bridge bar 41 which medially perforatedat 42 .tov slip 'over guide fpii`il'33 and thus' serve as a'guifde for the lower end of JCube v35. l' l Oi'itflow from .tank l0 vcontrolled by upward and downwardmovement of tube` l35 and for this purpose I provide an operating arm at one end hooked into enlarged substantially triangular openings in the upper end of tube 35 and at the other end carried by a stud 51- journaled inthe lower end of a lever 52 pivoted on a pin v53 carriedby a bracket 54` which is provided with a threadedstud 55 projectable through the wall of tank l0 and receiving a yclamping nut 56. l

Stud 55 is boredto receive an operating shaft 52 provided at its outer end with an operating handle 58 and at its inner end with a calin 59 adapted to engage a pin 60 on lever 52, the arrangement being such that, by rocking handle 58 in either direction from anormal position, cam 59 will act upon pin 60 to swing lever 52 to raise tube 35 and thus raise valve ring 36 from seat 3l.

In order that valve ring 36 may beheld away from seat 3l a suihcient length of' time and automatically permitted to return at the end ot such time, bracket 54 is provided with a dash-pot 62 and a'dash-pot piston 63 is mounted therein and connected to lever 52, the arrangement being such that opening movement of lever 52' is substantially unresisted and return movement is controllably resisted by the usual valve 64.

At the bottom of the dash pot 62 I'pro` vide a small by-pass 64u which permits a f rapid escape of the air past the piston 63 when the piston nears the limit of its stroke,

restriction.

In order that piston 63 may not be accidentally withdrawn from the dash-pot 62, said dash-pot is separably secured to bracket 54 by means of flange 66 and screw 67, a portion 68 of` the bracket `projecting over the open end of the dash-pot, when the parts are assembled, so as to obstruct withdrawing movement of they piston 63.

I claim as my' invention:

l. The combination, with a tubular flushingvalve extendingV above the normal water level, of a manipulator comprising a bracket, an operating lever pivoted on said bracket.y a manipulator shaft oiirnaled in sai-d bracket,

ico

liti' a cam carried by said shaft and acting upon the lever to swing said lever in one direction by movement of the shaft in either directionv from neutral, a dash pot secured to the bracket, and a piston mounted in said .dash pot and connected to said lever.

2. A flushing valve manipulator comprising a bracket, and operating lever pivoted on said bracket, a manipulating shaft jour-- naled in said bracket, a cam carried by said shaft kand act-ing upon the lever to swing said lever in one direction by movement of the shaft in either direction from the neutral position a dash-pot secured to the bracket, and a piston mounted in said ldash-pot 'and connected to said lever.

3. A flushing` valve manipulator comprising` a bracket, an opera-ting lever pivoted on said bracket, a manipulating` shaft journaled in said bracket, a cam carried by said shaft and acting upon the lever to swing said lever in one direction by movement of the shaft in either direction from a neutral position, a dash-pot detachably secured to the bracket and having` its mouth partially obstructed by a portion of the bracket, a piston mounted in said dash-pot and connected to said lever.

In Witness whereof, I have hereunto set my hand at Indianapolis, Indiana, this 10th day of November, A. D. 1925.
